WHAT ARE THE TRENDS INFLUENCING MINING
- Monitoring and Inspection - Mining is said to be one of the most hazardous industries for workers. Mining Operations stimulate numerous dangers such as rock falls, high humidity, gas-leaks, dust explosions, floods, and other unfortunate events affecting worker's safety. The mining industry has employed UAVs and Drone Technology for real monitoring and inspection of deep shafts. Inspection of mining equipment, which previously required a highly experienced workforce, can now be carried out in a comparatively inexpensive and time-efficient method. Depending upon Geographic Information Systems (GIS) and high-grade quality RGB sensors for obtaining data, the Drone Aerial images collected are more precise and reliable than any traditional monitoring and inspection method.
- Surveying and Mapping - Aerial surveying and mapping are one of the most excruciating and time-consuming activities that need regular implementation by the mining industry. With the assistance of high-quality drones and a proficient drone pilot on-site, the cost for detailed Aerial photography is 90% lesser than that of a traditional piloted plane. The GIS data captured can be transformed into 3D models and reliable ortho-images with significant volumetric measurements.
- Stockpile - Managing stockpiles in any industry for that matter is a cumbersome task, but essential for safety. A challenge faced continuously by the mining industry are the ever-changing heights and areas concealed by stockpiles at the job-site. The irregularity of such inventories makes it challenging to determine their volume with accuracy with conventional techniques like GNSS surveying. The traditional methodology for such operations prevents regular surveying and can even become a danger to the surveyor. With the help of drones, mining companies can yield vital information regularly and efficiently.
Photogrammetry software, 3D models, Digital Terrain Models (DTMs), Digital Elevation Models (DEMs) and even highly detailed contour maps are produced for comprehensive analysis of the stockpile.
- Haulage Road Optimization - Haul road networks hold an essential place in the efficiency and productivity of mining operations. For dependable and consistent transportation, roadway statuses and conditions must frequently be observed. By employing UAVs to capture Aerial data, regular visual evaluations of haul roads can take place. Obtaining relevant information such as length, slopes, and turning angles of the haul roads support engineers and constructors for meticulous preparation, designing, development and upkeep. Drones also accommodate areas more extensively and precisely to guarantee that the roads are constructed following legal standards.
- Mining Exploration - Mining exploration is easily one of the most life-threatening operations that were traditionally carried out by workers of the respective company. With Drone Technology redefining several aspects of the mining industry, the mining exploration has redesigned itself through the implementation of high-quality drones. With UAV data, mining companies can transform survey information into high-resolution orthoimages, DSM maps, RBG maps, etc. via secure photogrammetry software. Mining exploration projects are uncovered at only a portion of traditional survey expenses, and are done efficiently, saving lots of time for the company! Photogrammetry software transforms data for more comprehensive and straightforward knowledge.
- Tailing Dam Monitoring - Employing drones for the surveying and inspection of tailing dams eradicates any danger to workers who indulged in traditional manual surveying techniques.
Aerial imagery assists operators and planners to observe mine-site components like slopes on tailings dams frequently. With Drones, regular monitoring and preservation of dams can be done with no manual requirement close to the subject being managed. Thorough data analysis maintains the goodwill of the asset and avoids any failure.
- Water and Sediment - Drones in the mining industry can also prevent any interruptions in mining operations due to undesired or uncontrolled water and sediment flow. Accurate Drone imagery of flow and tailings operations are remodelled as Digital Elevation Maps (DEMs) for thorough perception and preparation by operators. Consistent visual records of the mine-site can be advanced for monitoring progress, guide planned activities, and regularly update financial audits.

DIFFERENT KINDS OF MAPS USED IN MINING
- Orthomosaic Maps - An orthomosaic map typically comprises numerous orthoimages. Aerial photography that is geometrically adjusted due to camera tilt, topographic relief, or lens distortion is known as an orthoimage. Every pixel on the photograph contains 2D and 3D Geo-tagged data, which supports the measurement of the actual distance between specific points on the map as it would be in real life. Orthomosaic plans allow area, volume, and distance of mine sites and projects to be measured correctly.
